Iranian President Masoud Pezeshkian on Tuesday warned the United States against threats, saying Tehran would honour its commitments if Washington did the same, but was fully prepared to defend itself if provoked.
"Mutual understanding is a two-way street. If the American side adheres to the agreement, we will also fulfill our commitments," Pezeshkian wrote on X.
"Our approach to unreasonable saber-rattling and baseless threats is to rely on rationality and human dignity in decision-making, and to defend decisively and fearlessly when it comes time to act," he added.
His remarks come less than two weeks after the United States and Iran signed the Islamabad Memorandum of Understanding on June 17-18. The agreement, signed remotely by US President Donald Trump and Pezeshkian, calls for an immediate end to military operations in Lebanon, the reopening of the Strait of Hormuz for at least 60 days, and a framework to address Iran's stockpile of highly enriched uranium.
The memorandum also launched a 60-day negotiating period, but disagreements have already emerged. Last week, the US and Iran gave conflicting accounts on whether Tehran had agreed to allow UN inspectors access to bombed Iranian nuclear sites. The ceasefire has also come under strain following Iran's temporary closure of the Strait of Hormuz, linked to renewed fighting between Israel and Hezbollah in Lebanon.
Pezeshkian's latest statement reaffirmed Iran's conditional commitment to the agreement while warning that any provocation would draw a response.
The ongoing negotiations are expected to address unresolved issues, including the future of Iran's nuclear programme, uranium enrichment levels and the possible release of up to $25 billion in frozen Iranian assets.
